The former world champions collide on Saturday night when David Benavidez takes on David Lemieux with the interim WBC super middleweight championship. The action takes from Gila River Arena in Glendale, Arizona, and airs live on Showtime beginning at 10 pm ET.

The fight winner also becomes one of several mandatory challengers for Saul "Canelo" Alvarez, putting another potentially massive prize on the table.

Benavidez (25-0, 22 KOs) has repeatedly shown that he is one of boxing's brightest talents, but his mistakes have kept him from bigger things in the past. He has twice lost the WBC super-middleweight championship, once after testing positive for cocaine and once for losing weight. Had Benavidez not been stripped for losing weight, he would have met Alvarez in the ring by now in the Mexican superstar's quest to unify all four world titles at 168 pounds.

With his power, toughness, and high-volume output, including a hammer blow, Benavidez will enter the ring a definite favorite at -2000.

Lemieux (43-4, 36 KOs) was a monster puncher at middleweight, scoring a knockout blow against Gabriel Rosado in 2014 before winning the IBF. 

The reward for Lemieux's world title win was a fight with the most feared man in the sport, Gennady Golovkin. However, things would go wrong, as he was much powered before an eighth-round stoppage. After continuing his campaign at middleweight, including a loss to Billy Joe Saunders in a WBO world title fight.

Lemieux moved up to 168 pounds in  2019.

Now riding a three-fight winning streak at super middleweight, Lemieux will look to take down one of the division's best fighters and set up a potentially huge fight in his next outing. Lemieux has one path to victory. It was an unfortunate reality, and that is to land a big, fight-changing blow. The problem is that Benavidez is talented, significant, and durable. Benavidez has all the upper hands in the fight, even if he allows himself to be drawn into a shootout instead of using his range working behind the jab. There's some question about whether Lemieux's full power load went up to 168, and he's the older, more diminutive guy with lots of miles on his body. It's tough to see the fight going in Lemieux's direction against such a daunting opponent.
